Baby No. 2 for 'It's Always Sunny' duo

Things continue to be Sunny for Kaitlin Olson and Rob McElhenney: The couple – and co-stars on FX’s It’s Always Sunny in Philadelphia – are expecting their second child together. Olson gave birth to Axel Lee just 13 months ago. “We’re having a boy! We’re so happy that Axel gets to have a brother so close in age. And I get to add another set of balls to my very, very male world,” Olson told People.
